printer wont connect

My canon MX 490 won't connect to my internet. I am told be T-Mobile that it is because the 5g bull. 
I have tried everything they suggested. Pissed

Toggle through your printer interface screen and see if there is a place to manually enter an "SSID" password (same as your 5G router password).  I had to mess with my printer for almost an hour before figuring it out.

I have the new, gris TMobile gateway and there are no setting options to change the SSID or transmission mode.

If you have the GRAY Nokia gateway, those settings can be changed.

Or, are you saying you have the BLACK Arcadyan gateway?

You will need to add a router like this one.  Just plug it in the back and you are set.

Give it the name and password you used before you hooker up the T-Mobile 5G.  My devices work perfectly now.

my new 5G Gateway Arcadia (black) has good service, and will "connect" but won't actually load content to any device. Plugged in my 6+ year old router to the Arcadian but and no luck with loading apps/internet pages. Should I buy a new router? 

I ended up buying a cheap router from Amazon to test. It's tplink brand or something. $25 if anyone wants the exact one let me know but you'd probably be better off with a mid/higher priced router. It was incredibly easy, I just plugged the ethernet port into the back of the kdv21. You can hook up any of the devices that you don't need to print from to the regular tmoble modem of you prefer and whatever you use to print hook up through the router but it doesn't matter you can hook everything up through the router. I would recommend Linksys or another reputable brand, I've had two Netgear combo modem routers (cheap and very expensive) and their customer service stinks.

follow Bukover’s advice!! It worked!!

The Cannon 452 should work on a separate 2.4 GHz SSID. Either add an additional SSID on the 2.4 GHZ radio or separate the current one and change the name/SSID to reflect the difference. 

Built-in wireless LAN (IEEE 802.11b/g/n)

If you don't like that solution or have issues with it add another router or an extender. The 803.11ax of these gateways doesn't play well with the older tech. Some might argue the older printers do not play nice with the newer 802.11ax. It is still the same problem. Compatibilidad 

Bukover rules!!!  My HP Office Jet 4630 now prints on the new 2.4Ghz frequency network I set up. Just tap the plus sign (+) on the T-Mobile Internet app "Manage your Wi-Fi networks" page to set up the second network.

Ran into the same issue. Printer wouldn't connect.. created the new network at 2.4… but now the question is… can I only print if my device is connected to the 2.4 network? I can't print from the faster original network can I?

This works! Just to clarify:

From the T-Mobile Internet app, choose RED at the bottom.

This takes you to the "Manage your Wi-Fi networks" page. Click on the plus sign at the bottom.

This takes you to "Update network." Under Wi-Fi network name (SSID)" write the name of a new network (your choice).

Next line, set a password.

Under “Frequency band” choose “2.4 GHz”;

under “WPA Version” choose “WPA/WPA2”. 

This will automatically set the next box "WPA Encryption Mode" to TKIP & AES. That's fine. Don't change it.

Click SAVE.

That does it. Hopefully it will work as well for you as for me.
